The stimulation settings can be adjusted as a patient's condition changes over time. The doctor programs the stimulator settings with a wireless device.
The patient uses a handheld controller to turn the DBS system on and off.
It is placed under the skin and runs from the scalp, behind the ear, down the neck, and to the chest. Extension – an insulated wire that connects the lead to the neurostimulator.It is placed inside the brain and connects to an extension wire through a small hole in the skull. Lead – a coated wire with a number of electrodes at the tip that deliver electric pulses to the brain tissue.It is placed under the skin of the chest below the collarbone or in the abdomen. Neurostimulator – a programmable battery-powered pacemaker device that creates electric pulses.Because the left side of the brain controls the right side of the body and vice versa, DBS is commonly performed on both sides of the brain.Ī DBS system has three parts that are implanted inside the body: The electrodes are connected by an extension wire to a battery-powered stimulator placed under the skin of the chest. Electrodes are placed deep within the brain through small holes in the skull. Overview of a deep brain stimulator (DBS). When turned on, the stimulator sends electrical pulses to regulate the faulty nerve signals causing tremors, rigidity, and other symptoms.įigure 1. The electrodes are connected by long wires that travel under the skin and down the neck to a battery-powered stimulator under the skin of the chest (Fig. The electrodes are placed on both the left and right sides of the brain through small holes made at the top of the skull. In deep brain stimulation, electrodes are placed in a specific area of the brain depending on the symptoms being treated.
Successful DBS allows people to potentially reduce their medications and improve their quality of life. DBS can help reduce the symptoms of tremor, slowness, stiffness, and walking problems caused by Parkinson's disease, dystonia, or essential tremor. Similar to a heart pacemaker, a neurostimulator uses electric pulses to regulate brain activity. Electrodes are placed deep in the brain and are connected to a stimulator device. Deep brain stimulation (DBS) is a surgery to implant a device that sends electrical signals to brain areas responsible for body movement.
